Patent CA-2279690-A1 (CA)
Inventor: CAMPO JOSEPH M
IPC: E04B1/26
Filed: 1999-08-06
Abstract: The traditional method of framing energy efficient Southwestern custom built homes entails the framing of an exterior wall and a second wall which is inside the exterior wall. All of this framing is done on site, and most frequently, in less than ideal weather conditions.      It is more efficient to erect wall unit assemblies built in the controlled and more productive environment of a shop. A wall unit assembly is built with a multiplicity of double stud units each unit having an interior load bearing vertical stud, and an exterior upright stud, an upper connecting member extending laterally between top end portions of the interior and exterior studs, and a lower connecting member extending laterally between bottom end portions of the interior and the exterior studs. The studs and connecting members preferably are made from dimension lumber, and fastened together by connecting plates. The double stud units are spaced along, and fastened above two parallel footers, and beneath two parallel headers thereby forming a wall unit assembly. Window, door, and straight wall unit assemblies are disclosed so that the walls of an entire building may be quickly erected using these prefabricated unit assembliess.

Title: Language analysis system and method
Inventor: ISHIKURA HIROSHI
IPC: G06F17/27
Filed: 1998-03-04
Abstract: A system capable of carrying out accurate language analysis. A given sentence is divided into tokens, and the parts of speech thereof are determined. When the part of speech of a token cannot be uniquely determined, the part of speech is determined on the basis of the parts of speech of the preceding and subsequent tokens. Then, the attribute of the predicate is analyzed by using suffixes or the like. Then, local structural analysis and determination of the function are carried out by matching the function and the part of speech. After that, overall structural analysis is carried out by extraction of a subordinate clause and analysis of the sentence pattern. In accordance with the overall structural analysis, local structural correction is carried out, if necessary.

Inventor: HABEL RICHARD ACHILLE
IPC: H03L7/183
Filed: 1999-11-10
Abstract: A simple phase locked loop (PLL) operates over a broad continuous range of frequencies, a range much larger than one octave but requires only an octave VCO. The Q of the PLL is controlled to within a factor of two at every frequency on the broad continuous range. The PLL enables the invention of a clock recovery circuit that operates at any bit-rate on a broad, continuous range of bit-rates. The bit-rate independent clock recovered by the PLL has equivalent fitter performance at all bit-rates. The PLL may be used to provide 3R transponder/regenerators with read/write access to overhead data, eye quality assessment, monitoring/identification of the bit-rate of the signal, and with bit-rate independent digital multiplexing and demultiplexing functions.      Such a 3R transponder/regenerator may also enable addition of overhead data to the digital signal, independent of the format or bit-rate of the digital signal. Bit-rate independent digital multiplexing and demultiplexing enable the interconnection of electronics in the 3R transponder/regenerator, or provision of digital signals to other functional blocks, at the lower demultiplexed bit-rate.

Title: Enhanced production of bridged hafnocenes
Inventor: DESOTO TROY E
IPC: C07F7/00
Filed: 1998-06-17
Abstract: The reaction between a hafnium tetrahalide-diamine adduct and a metallated bis(cyclopentadienyl-moiety containing) ligand, offers great promise as a way of producing racemic hafnocenes, but involves a number of complications. Tetrahydrofuran, a commonly-used solvent/diluent for such reactions, when present in substantial portions in the liquid reaction medium containing the reactants and/or reaction product(s) has been found to cause a substantial reduction in yields of chiral hafnocenes. Apparently the presence of a substantial amount of THF causes or at least results in the formation of increased amounts of the undesirable meso isomer, tends to cause or result in tar formation, and results in a product having poor filterability. Thus large amounts of THF if fed to the reactor with the reactant(s) are purged to a suitably low level, replaced by a liquid aromatic hydrocarbon, and then the reaction mixture is heated to a higher reaction temperature. Large amounts of liquid paraffins and free diamine in the reaction mixture during reaction also contribute to tar formation and reduction in yields of chiral hafnocene. Thus the presence of such materials in the reaction mixture is kept to a minimum. These process modifications make it possible to increase yields of the chiral hafnocene, to reduce formation of the meso isomer, and to sharply reduce the amount of tar formation in the synthesis of chiral hafnocenes from diamine adducts of hafnium tetrahalide and metallated bis(cyclopentadienyl-moiety containing) ligands. Moreover, the hafnocene reaction product so formed has significantly improved filterability characteristics.

Title: I/o forwarding in a cache coherent shared disk computer system
Inventor: KLOTS BORIS
IPC: G06F12/08
Filed: 1998-10-05
Abstract: A method and apparatus for I/O forwarding in a cache coherent shared disk computer system is provided. According to the method, a requesting node transmits a request for requested data to a managing node. The managing node receives the read request from the requesting node and grants a lock on the requested data. The managing node then forwards data that identifies the requested data to a disk controller. The disk controller receives the data that identifies the requested data from the managing node and reads a data item, based on the data that identifies the requested data, from a shared disk. After reading the data item from the shared disk, the disk controller transmits the data item to the requesting node. In one embodiment, an I/O  destination handle is generated that identifies a read request and a buffer cache address to which the data item should be copied. The I/O destination handle is transmitted to the disk controller to facilitate transmission and processing of the data item from the disk controller to the requesting node. As a result of forwarding data that identifies the requested data directly from the managing node to the disk controller ("I/O  forwarding"), the duration of a stall is reduced, contention on resources of the system is reduced and a context switch is eliminated.
